' IMPROVEMENT IN GANG-PLOWS.

Specification forming part of Letters Patent No. 197,159, dated November13, 1877 application filed 1 August 4,1877. 4

To all whom it may concern:

Be it known that I, CHARLES MOWREY, of Stockton, county of San Joaquinand State of California, have invented an Improvement in Gang-Flows; andI do hereby declare the following to be a full, clear, and exactdescription thereof, reference being hadto the accompanyin g drawings.

My invention relates to certain improvements in gang-plows of that classin which a number of plows are secured to a suitable frame, (usuallytriangular and it consists in a novel manner of mounting the frame uponbearing wheels, and in a device by which the frame and plows can bedepressed, so that the plows will take the ground, or by which the powerof the'team will raise them out of the ground, together with certaindetails of construction.

In the accompanying drawings, Figure 1 is a perspective view. Fig. 2 isa side elevation, and Fig. 2 a detail view.

A is the frame of my plow, and it carries the plows B B B, which aresecured to the frame by standards 0. These standards pass through twodisks or plates, D, one above and one below the frame, fitting with ashoulder against the upper plate,-and held in place by a nut, E, whichscrews upon the upper end of the standard. The disks are bolted throughthe frame to each other, so that the whole is very solid. The rear endof the plow-frame is supported upon a single wheel, F, and the front isconnected with the bolster of a pair of wheels, G, by strong arms H,which are so bent as to allow the wheels to be cramped in eitherdirection without touching the frame or arms.

In order to raise and lower the plows and frame, and control theirmotion so that they shall not be unwieldy, I have mounted the frame insuch a manner that by means of mechanism it can be adjusted at will.

The rear wheel F has its axle secured in a link, I, which is journaledto the plow-frame at some point J in front of the wheel-axle, as shown.The rear end of the link has an internal gear or segment, K, formed uponone side. The link is slotted in a curve corresponding with the radiusabout .which it moves, and a lever, L, has the pin forming its center ofI motion passing through the slots.

The rear end of the lever is formed into a segment-pinion, which mesheswith the internal segment K, before described 5 and it will be seen thatany motion of the upper end of the lever will, by the action of thepinion upon the segmentrack, raise and lower the plow-frame about thepoint of suspension J of the link. The arms H have their front endsjournaled to links M, and these links are rigidly secured to a shaft, N,which extends across the front of the bolster O, turning in boxes. Ahand-lever, P, is keyed to this shaft, and extendsup so as to be withinreach of the driver. A notched arc, Q, is secured by its side, and aspring-pawl, R, serves to hold the lever at any point on the are. Thispawl has an arm extending up to the lever-handle, so that it may beeasily operated to move the pawl. From the lever P a rod, S, extendsback, and is pinned to a slidin g guide, T, which can be moved forwardand back in boxes upon the plow-frame, as shown. A rod, U, also extendsfrom the lever L to the guide T; and it will be manifest that when thelever P is moved forward there will be a simul:

'taneous and parallel action of the lever L, and

the plows will thus be depressed to take as much ground as may bedesired.

When it is desired to raise the plows and frame it will only benecessary to raise the pawl from the notched rack Q,when thepower of theteam exerted upon the axle and front wheels will cause the links M andlever P to rotate backward about the shaft N, this movement being alsocommunicated to the lever L, so that the retarding of the plows willcause them to be lifted at once out of the ground without any manualpower being exerted.

The front wheels G may be made of different size, if desired, toaccommodate them to the land and furrow; or they may be mounted to turnupon crank-arms V at the end of the axle W. The sleeve which fits theaxle has its inner end toothed, as shown at X, and an enlargement uponthe axle is similarlynotched or toothed, so that by means of a nut, b,at the end of the axle these teeth may be firmly interlocked, so as toset the crank-arm at any angle to suit any furrow.

The bolster O has a broad-flanged or cupshaped disk, Y, secured to itslower slide, and

a boss, Z, projects from its centersr A circa"- lar plate, a, is securedto the axle-bed, and fits into the cup-shaped disk of the bolster, theboss passing througha hole in the center. The king-bolt passes throughthis boss and unites the axle and bolster firmly together, and broaddisks give a hearing which prevents the rocking of the bolster andplow-frame, while the boss relieves the king-bolt of the strain whichwould otherwise be brought upon it.

Having thus described my invention, what I claim, and desire to secureby Letters Patent, is-

1. The bent arms H, supporting the front of the frame A, and journaledin the links or arms M, which project from the shaft N, said shaftturn'i ug in boxes upon the bolster 0am provided with the lever P sothat the plow tJHARLES' MGWREY. [11. s.] Witnesses:
